Housing

Abstract

A housing having a flat portion and a curved portion is provided. The housing includes an upper material layer, a lower material layer and a core layer. The core layer is disposed between the upper material layer and the lower material layer. The core layer has a first material region and a second material region. The first material region is corresponding to the flat portion. The second material region is corresponding to the curved portion. A material of the first material region is different from a material of the second material region.

What is claimed is: 
     
         1 . A housing having a flat portion and a curved portion, the housing comprising:
 an upper material layer;   a lower material layer; and   a core layer, disposed between the upper material layer and the lower material layer, wherein the core layer has a first material region and a second material region, the first material region is corresponding to the flat portion, the second material region is corresponding to the curved portion, and a material of the first material region is different from a material of the second material region.   
     
     
         2 . The housing as recited in  claim 1 , wherein the material of the first material region is metal, and the material of the second material region is plastic. 
     
     
         3 . The housing as recited in  claim 1 , wherein the material of the first material region is plastic, and the material of the second material region is metal. 
     
     
         4 . The housing as recited in  claim 1 , wherein the upper material layer is a carbon fiber layer, a glass fiber layer, a Kevlar fiber layer, a metal layer or a plastic layer, and the lower material layer is a carbon fiber layer, a glass fiber layer, a Kevlar fiber layer, a metal layer or a plastic layer. 
     
     
         5 . The housing as recited in  claim 1 , wherein a material of the upper material layer is different from a material of the lower material layer. 
     
     
         6 . The housing as recited in  claim 1 , wherein the curved portion surrounds the flat portion. 
     
     
         7 . The housing as recited in  claim 1 , wherein the second material region extends from the curved portion to the flat portion so that boundaries of the first material region and the second material region are located within the flat portion.
